BRAKE-BEAM surronr.

To all whom it may concern Be it known that I, THOMAS L. BURTON, a citizen of the United States, residing at St.

bars which extend beneath the brake beam for preventing the same from falling upon 1-5 the track in case of emergency, and which may also be used for carrying a third point support for the brake beam, are usually attached to the spring plank of the truck frame, and the object of my present inven- 20 tion is to provide an improved hanger support whereby a single rigid' or integral supporting bar may be readily applied'bodily to the hanger by a lateral or transverse movement and be held thereon against longitudinal movement, without the use of bolts,

clamps or other adjustable parts for look? ing the bar in position. For this purpose, my improvement) comprises a suitable bracket or hanger having an open recess or socket formed therein and a rigid bar having a portion formed to be inserted and lit within said socket and prevent longitudinal movement of the bar therein.

In the accompanying drawing: Figure 1 is a side elevation of one form of a safety bar and support embodying my improvement; Fig. 2 a transverse section of the bartaken through the spring plank of the truck; Fig. 3, a side view showing a spring link as a third point support from the bar to the brake beam; and Fig. l, a side view showing a short supporting bar serving as an emergency support only. 0

According to the form of my improvement illustrated in the drawing, there is attached to the spring plank 26 of the truck frame, one or more brackets or hangers 31, having formed therein recesses or sockets 32, open at the upper end. There are preferably two of such hangers, one at each side of the spring plank, for each safety bar, as inclicated. The bar 25 is provided with an offset portion 30 formed to be inserted and fit within the recess or socket 32 of the hanger, the offset portion also forming shoulders 33, which engage the hangers and Specification of Letters Patent,

The bar may also be readily applied or re moved from the hangers at any time by a simple transverse or lateral movement and it is securely held in position during operation as it cannot be tilted vertically in case one of the brake beams should fall upon it, nor canit be displaced longitudinally in the hangers as the shoulders or projections engage the sides of the hangers and prevent such movement.

Having now described my invention what desire to secure by Letters Patent is:

l. A brake beam support, comprising a hanger attached to the truck frame and having a socket, and a safety bar extending beneath the truck frame and brake beam and having a portion formed to be inserted and. it within the socket and held therein against longitudinal movement.

2. A brake beam support, comprising a hanger attached to the truck frame and having a socket, and a safety bar extending beneath the brake beam and having an offset portion adapted to be inserted laterally into said socket and held therein against longi tudinal movement.

3. A brake beam support, comprising a hanger attached to the truck frame and having an open socket, and a safety bar extending beneath the truck frame and brake beam and having a portion formed to be inserted laterally into the socket and held therein against longitudinal movement.

4. A brake beam support, comprising a hanger attached to the truck frame and having an open socket, and a safety bar extending beneath the brake beam and having an intermediate offset portion formed to be inserted laterally into said open socket and held therein against longitudinal movement.

5. A brake beam support, comprising a hanger attached to the truck frame and having an open socket, and a safety bar extending beneath the brake beam and having an offset portion formed on a curved section and adapted to be inserted laterally into said open socket and held therein against longitudinal movement.

6. A brake beam support, comprising a hanger having an open socket, and a safety bar extending beneath the brake beam and having an integral portion formed to fit said socket and provided with a shoulder for engaging the hanger to prevent longitudinal movement therein.

7. A brake beam support, comprising a hanger having an open curved socket, and a safety bar having anoffset curved portion formed to fit said socket and adapted to be inserted therein by a lateral and partial rotary movement.

8. A brake beam support, comprising a hanger having an open socket, and a safety bar extending beneath the truck frame and brake beam and having a portion formed to be inserted laterally into and fit within said socket so as to prevent accidental vertical displacement of the bar in said hanger.

9. A brake beam support, comprising a pair of hangers attached to the spring plank of the truck, and each having an open socket, and a single integral safety bar extending beneath the brake beam and having a portion formed to fit within the sockets, said bar being adapted to be applied laterally to said hangers and provided with means for preventing longitudinal move ment therein.

10. A brake beam support, comprising a hanger having a curved open socket, and a safety bar extending beneath the brake beam and having an integral curved offset portion formed to fit into said socket when applied laterally thereto and providedwith means for preventing vertical and longitudinal displacement of the bar in the hanger,

In testimony whereof I have hereunto set m hand.
